At this time, it will lead to deformation of the pipe section, especially the ovalization of the pipe section that can be connected to the rotor / generator set
The disadvantage is that such deformations have to be suppressed by a rather high material investment

Embodiment Construction

[0019] first reference Figure 5 , the figure shows a conventional rack 1 . The frame 1 connects a rotor / generator unit 2 to a tower 3 of a wind energy installation. A rotor 4 of the rotor / generator unit 2 is in direct drive connection with a generator 5 without gearing. The rotor / generator set 2 is connected to the frame 1 via a generator 5 . The frame 1 is rotatable about an axis 6 on the tower body 3 .

[0020] The frame 1 contains two conical pipe sections 8 and 9 . The two tube sections 8 and 9 are connected to one another at 10 via end edge surfaces facing one another, forming a continuous tube lumen.

[0021] In particular, the dynamic forces transmitted by the rotor 4 act upon the machine frame 1 , forming a certain critical load at 11 . The ovalization of the pipe section 9 caused by these loads can only be suppressed insufficiently by means of the point-shaped reinforcing spacers indicated at 12 .

Abstract

The invention relates to a machine support for receiving a rotor / generator assembly (2) of a gearless wind energy plant, wherein the machine support (1) connects the rotor / generator assembly (2) to the tower (3) of the wind energy plant, is mounted rotatably on the tower (3) and comprises pipe sections (8, 9) which are arranged at an angle to each other and one (9) of which can be connected to the rotor / generator assembly (2) and the other (8) can be connected to the tower (3). According to the invention, the pipe section (9) that can be connected to the rotor / generator assembly (2) is connected to the lateral surface of the other pipe section (8) by way of an end edge surface facing away from the rotor / generator assembly, and the lateral surface of the other pipe section (8) extends into the region surrounded by the connection (10).

Description

technical field [0001] The invention relates to a frame for accommodating a rotor / generator set of a wind power plant without gear, which frame connects the rotor / generator set to a tower body of a wind power plant, the frame being rotatably mounted on the tower body, and the frame contains interconnected, angled pipe sections, one of which can be connected to the rotor / generator set and the other can be connected to the tower body. Background technique [0002] From use, a frame is known, the pipe sections of which are connected to each other via end edge faces facing away from the rotor / generator set or facing away from the tower. The frame is under high static loads, but above all under high dynamic loads. At this time, it will cause deformation of the pipe section, especially the ovalization of the pipe section that can be connected to the rotor / generator set. The disadvantage is that such deformations have to be suppressed by a relatively high material investment. C...
